Itekhnoloji yokuvelisa izixhobo zombhobho wesinyithi esityhidiweyo-ukuphoswa kwesanti
1.Isanti intshayelelo yokuphosa.
Ukuphoswa kwesanti kusetyenziswa ukwenza iindawo ezinkulu. Isinyithi esinyibilikisiweyo sigalelwa kwindawo yokubumba eyenziwe ngesanti. Indawo ekule santi yenziwa ngokusebenzisa ipateni, edla ngokwenziwa ngomthi, ngamanye amaxesha ibe yintsimbi. Indawo yokubumba ikwindawo ehlanganiswe kwibhokisi ebizwa ngokuba yiflaski. I-core yimilo yesanti efakwa kwi-mold ukuvelisa iimpawu zangaphakathi zenxalenye efana nemingxunya okanye iipaseji zangaphakathi. Ii-cores zifakwa kwindawo yokubumba ukwenza imingxunya yeemilo ezifunwayo.
2. Inkqubo yokubumba isanti:
Kwimold enamacandelo amabini, eqhelekileyo kwisanti, isiqingatha esiphezulu, kuquka isiqingatha esiphezulu sepateni, iflask, kunye necore sibizwa ngokuba yi-cope kwaye isiqingatha esisezantsi sibizwa ngokuba yi-drag. Umgca wokwahlula okanye umphezulu wokwahlula ngumgca okanye umphezulu owahlula i-cope kunye ne-drag. Ukutsala kuqala kuzaliswa ngenxalenye yesanti, kwaye ushicilelo oluphambili, ii-cores, kunye nenkqubo ye-gating zibekwe kufutshane nomgca wokwahlula. I-cope emva koko idityaniswe kwiyeza, kwaye isanti igalelwa kwisiqingatha se-cope, igubungela ipateni, icore kunye nenkqubo ye-gating. Isanti iqiniswa ngeendlela zokungcangcazela kunye neendlela zoomatshini. Okulandelayo, i-cope isuswa kwiyeza, kwaye ipateni isuswa ngononophelo. Injongo kukususa ipateni ngaphandle kokuphula umngxuma we-mold. Oku kwenziwa lula ngokuyila idrafti, i-angled encinci ukusuka kwi-vertical ukuya kwi-vertical surfaces yepateni.
3. Iingenelo zokufakelwa kwemibhobho yesinyithi esityhidiweyo kusetyenziswa isanti eluhlaza yodongwe
Isanti eluhlaza yodongwe: isanti enodongwe kunye nomlinganiselo ofanelekileyo wamanzi. I-Binder ephambili, eyenziwe ngqo emva kokubumba isanti kunye nokugalelwa kwindawo emanzi. Ukwenziwa kwesanti eluhlaza kunembali ende kwaye kusetyenziswa kakhulu. Iingenelo zayo zezi:
- Izinto eziluhlaza zibiza kancinci kwaye zininzi.
- Isampuli yesanti ngaphandle kokomisa, umjikelo wemveliso omfutshane kunye nokusebenza kakuhle, ngoko ke kulula ukufikelela kwimveliso enkulu.
- Kwisanti endala, i-bentonite engandiswanga exutywe namanzi iyakwazi ukubuyisela amandla, ukuphinda isetyenziswe kwesanti endala kunye nokusetyenziswa kwakhona kotyalo-mali oluphantsi.
- Emva kokusetyenziswa ixesha elide, siye saphuhlisa uluhlu lwezixhobo zokubumba.
- Ukuchaneka kobukhulu bezinto ezibunjiweyo eziveliswa yisanti eluhlaza yodongwe kuyafana notyalo-mali olubunjiweyo.
Ngenxa yezi nzuzo, inkqubo yesanti eluhlaza yodongwe kwii-castings ezincinci, ingakumbi iimoto, ii-injini, ii-looms kunye nezinye iimveliso ezininzi zentsimbi ephosiweyo iye yasetyenziswa kakhulu, umlinganiselo wezikhundla zayo kuqala kwi-cast. Nangona kunjalo, xa i-casting yesanti eluhlaza yodongwe, i-vaporization yamanzi kunye nothutho lwesanti, okwenza i-casting ibe lula kwi-blowhole, isanti, umngxuma wesanti, ukudumba, isanti enamathelayo kunye nezinye iziphene.
